To examine in detail the health-care utilization patterns of maltreated children, we studied electronic health records (EHRs) of children assigned maltreatment-related codes in a large medical system. We compared youth with maltreatment-related diagnoses (N = 406) with those of well-matched youth (N = 406). Data were based on EHRs during a 4-year period from the University of Minnesota's Clinical Data Repository, which covers eight hospitals and over 40 clinics across Minnesota. A primary care provider (PCP) was assigned to over 80% of youth in both groups. As expected, however, the odds of not having a PCP were twice as high in the maltreated as in the comparison group. Also as expected, maltreated youth had higher rates of emergency department visits. We ruled out differences in age, gender, race, public insurance, duration in the medical system, type of specialty department, and clinic location as potential explanations for these differences. On the other hand, there were no significant differences between maltreated and comparison youth in hospitalizations, preventive visits, or office visits. Contrary to expectations, maltreated youth were not in the medical system for just a brief period of time and were not more likely to cancel or miss appointments. The current study adds to the research literature by providing more detailed information about the nature of health-care services used by children with maltreatment-related diagnoses.
